Free Grammarly


Grammar mistakes happen to the best of us. Sometimes, we hit send on an email too quickly, or we forget to double-check our cover letters. Grammarly checks for grammatical errors automatically to help you avoid embarrassing mistakes. We have a world-class team of linguists who work daily to improve our algorithms and make Grammarly’s grammar and spell checker as close to a human proofreader as possible. While other spell checkers might let you down when it comes to dangling modifiers or split infinitives, Grammarly won’t. Additionally, our application learns your writing style and allows you to toggle between style categories, so that your editor is always relevant to your writing.

Proper punctuation can get confusing. What is an Oxford comma, anyway? Do you really need that many exclamation points? When should you be using a colon? In addition to checking your spelling, Grammarly corrects punctuation errors, too. Say goodbye to comma splices, errant semicolons, and other pesky punctuation issues.

Sometimes, we get so excited when we’re writing that we might accidentally skip a letter or type a homonym of the word we really mean. Grammarly has you covered in case of a spelling emergency. With just one click, you can correct spelling mistakes and avoid embarrassment. Our application also has a built-in dictionary, accessible wherever you write, that examines contextual spelling (this means we’ll let you know when you accidentally type “there” when you meant “their”).

Grammarly, the world’s most accurate grammar and spelling checker, is trusted by millions of people. As you type, Grammarly checks your text against more than 250 advanced grammar rules. The checks include common grammatical errors, such as subject-verb agreement, article use, and modifier placement, in addition to contextual spelling mistakes, phonetic spelling mistakes, and irregular verb conjugations. Plus, Grammarly’s spell check takes the context of your sentence into account.

Grammarly checks for spelling mistakes, grammatical mistakes, vocabulary issues, and plagiarism while you type. You’ll receive suggested corrections via Grammarly Cards, which offer straightforward explanations of your mistakes. Each time you make a correction, you’ll also learn how to avoid making the same mistake in the future. You’ll see your writing improve dramatically with Grammarly as your own personal editor and grammar coach.
